Hardware, or the driver, should drop frames which fail the FCS, well
before bpf comes into play. This typically gets done at the same point
where, e.g., giant or runt frames are dropped.

Agreed that ti's interesting.  I would still like to see the output of
ifconfig (check to see if outboard TCP/ip acceleration is enabled)
and	
	netstat -s -p tcp
	netstat -s -p ip

on the machines involved.  ssh sessions to or from the bridge itself
would also be interesting.
